Speeding up PHPUnit startup when code coverage is not required

I am using PHPUnit in my Codeception unit tests. I am not interested in code coverage yet, so I would like to completely disable it, especially because it delays my tests by 8..12 seconds. This becomes annoying when tests are configured to be run automatically when files change.

I debugged PHPUnit code to see why it is starting up so long and found out that it spends up to 12 seconds inside getCodeCoverageFilter looping through getBlacklistedDirectories and collecting filenames calling addDirectoryToBlacklist.

Is there any way to disable processing getCodeCoverageFilterin Codeception or PHPUnit itself without directly hacking its code?

Here is my current phpunit.xml at the root of my Laravel 5 project:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
         backupStaticAttributes="false"
         bootstrap="bootstrap/autoload.php"
         colors="true"
         convertErrorsToExceptions="true"
         convertNoticesToExceptions="true"
         convertWarningsToExceptions="true"
         processIsolation="false"
         stopOnFailure="false"
         syntaxCheck="false">
    <testsuites>
        <testsuite name="Application Test Suite">
            <directory>./tests/</directory>
        </testsuite>
    </testsuites>
    <filter>
        <blacklist>
            <directory>./vendor/</directory>
            <directory>./database/</directory>
            <directory>./public/</directory>     
            <directory>./resources/</directory>
            <directory>./storage/</directory>
            <directory>./tests/</directory>
        </blacklist>
        <whitelist>
            <directory suffix=".php">app/</directory>
        </whitelist>
    </filter>
    <php>
        <env name="APP_ENV" value="testing"/>
        <env name="CACHE_DRIVER" value="array"/>
        <env name="SESSION_DRIVER" value="array"/>
        <env name="QUEUE_DRIVER" value="sync"/>
    </php>
</phpunit>

According to codeception documentation, the code coverage is enabled in codeception.yml. Try:

coverage:
    enabled: false

Or removing the key.

Just remove the line

<log type="coverage-html" target="coverage"/>

from your phpunit.xml

In fact, I use two xml files.

One standard phpunit.xml that is used on a remote code inspection service, and one that I specifically named phpunit_no_code_coverage.xml without code coverage, that I use locally while developing.

You can specify which xml file to use via phpunit's c flag, e.g:

./phpunit -c tests/phpunit_no_code_coverage.xml --testsuite suite_name

The result is rather huge, my testsuite runs now rather fast, on average taking ~15 seconds, whereas it before took 110 seconds.
